| Threshold Zone |
| broader | the:Interpretation, the:Composition, the:SpatialCompositionStrategy |
| definition | A horizontal zone at the base of a composition that separates the viewer's implied space from the depicted gathering or social field. Functions as both an entry point for the eye and a structural hinge between observer and scene. |
| editorialNote | Source: 20260309. Broader updated to SpatialCompositionStrategy. Identified as a recurring compositional habit across multiple paintings: Alhambra courtyard (dark pavement), Seoul palace (sandy ground with shadows), St. Mark's (acqua alta reflections). ChatGPT's EdgeObserverViewpoint discarded as a thinner restatement. |
